We feel love. We think about it. But we aren't even aware we aren't giving it a voice or expression. One of the hardest, and most beneficial acts you can do is ask those close to you. How do you know that I love you? How do I show it? When do you feel it? And then listen. Take it seriously. Make some choices.
What you hear may hurt, but don't discount, or run or get angry; because it may also change your relationships and the health of your family.
